SPECIFICATION forming part of Letters Patent No. 345,208, dated July 6,1886.

Application filed April 2, 1886. Serial No. 197,578. (No model.)

To all whom it may concern.-

Be it known that I, HENRY A. BEHN, of Union Hill, in the county ofHudson and State of New Jersey, have invented certain new and usefulImprovementsin Machines for Winding Sewing-Machine-Shuttle Bobbins; andI do hereby declare the following to be a'full, clear, and exactdescription of the invention, such as willenable others skilled in theart to which 1t pertains to make and use it, reference being had to theaccompanying drawings, which form part of this specification.

I My invention relates to machines forwind- 1ng sewing-machine-shuttlebobbins; and it consists in, first, the combination with the revolvingshafts and a driving mechanism for causing them to revolve, with thebobbins placed thereon, of the disks, provided with hooks and placedbetween the bobbins; second, a disk having recessed sides, so as tocorrespond to the shapes of the bobbins, and provided with a hook forthe purpose of trans ferring the thread from one bobbin to the other;

third, the combination of the shafts upon which the bobbins are placed,a mechanism for driving them, the disks placed between the bobbins, asliding carriage which guides and moves the threads from one bobbin toanother, and mechanism, substantially as described, for shifting thecarriage and moving the threads as fast as the bobbins are filled;fourth, the combination of the driving-shaft, provided with pulleys, theshafts for revolving the bobbins and which are provided with pulleys,the belts for driving the shafts, the shafts on which the bobbins areplaced, the hooked disks, the sliding carriage, and mechanism for movingthe carriage; fifth, the combination of the driving-shaft,a train ofreducing-wheels, the vertical shaft having a wheel with an arm securedto its upper end, the springactuated slide carrying a dog, theratchet-wheel, a spurwheel, the carriage, the tension devices forholding the threads, the bobbin-shafts, operating mechanism for causingthe bobbinshafts t0 revolve, and the disks; sixth, in a bobbinwindingmachine, the combination of the shafts upon which the bobbins, areplaced, with the disks which separate the bobbins, and which areprovided with hooks and V-shaped edges,

all of which will be more fully described hereinafter.

The object of my invention is to produce a bobbin-winding machine inwhich any desired number of bobbins are placed upon the same ordifferent shafts, and in which the bobbins are successively filled, andthe threads automatically shifted to other bobbins as fast as thebobbins are filled, and which will require no care or attention upon thepart of the operator, except when the bobbins have all been filled, whenthe machine will have to be stopped for the purpose of removing theshafts upon which the filled bobbins are placed, in order to replacethem with empty ones.

-Figures 1 and 2 are side elevations taken from opposite sides of amachine embodying my invention, Fig. 1 being partly in section. Figs.

3 and 4 are end views. Fig. 5 is a plan view. Figs. 6, 7, and 8 aredetail views. Fig. 9 is a detail View showing the clamp, and Fig. 10 isan enlarged detail View of the supporting device or table and clamp.

A represents a suitable frame-work of any desired construction, and inwhich the main driving shaft B is journaled. This shaft is provided atits outer end with tight and loose pulleys 13*, in the usual manner, sothat the belt can be shifted and the machine instantly stopped, Wheneverso desired. The boxes to, in which this shaft is journaled, are madevertically adjustable, so that the shaft can be moved at any time inorder to enable a larger or a smaller wheel or gear, 0, to be placedupon its inner end. ,As shown in Fig. 6, both boxes a are slotted neartheir lower ends, and through these slots are passed screws or bolts, awhich hold the boxes in any positionin which they have been adjusted.This change in gears is made for the purpose of varying 90 the number ofrevolutions which the main shaft shall make before the shiftingmechanism is made to move for the purpose of transferring the threads toother bobbins. By this construction larger or smaller sewing-machinebobbins can be filled, as may be desired. It is the intention to givethis main driving-shaft, for instance, six hundred revolutions beforethe shifting mechanism is moved, to fill. one size of bobbins; but if alarger or smaller bob- 100 bin is substituted, the time at which theshifting mechanism must be moved is varied according to the size of thebobbins which are to be filled. Upon this main driving-shaft B areplaced a number of tight pulleys, D, from which extend belts D, whichpass around corresponding pulleys, E, upon the shafts F, which drive thebobbin holding shafts G. The bobbin-holding shafts G are supported atone end by suitable adjustable boxes or supports, H, and are connectedto the shafts F by means of suitable connecting devices. In the presentinstance there is placed a disk, I, upon the end of the shaft F, andthis disk is provided with a hole at its center to receive the end ofthe bobbinholding shaft, and a slot, .I, in its periphery to receive acorresponding projection, K, upon a corresponding disk, L,

upon the bobbin holding shaft. \Vhen the shaft F is made to revolve bythe driving belts and pulleys, the shaft holding bobbin is made torevolve at the same time. There may be any desired number of thesedriving shafts F and bobbin-holding shafts G, according to the number ofbobbins which are to be filled.

Upon each bobbin-holdin g shaft G are loosely placed a suitable numberofbobbins of any description,and in between every pair of bobbins isloosely placed a disk, M, having concaved sides, so as to correspond tothe shapes of the bobbins, and each disk M is provided with a hook, N,and V-shaped edges,as shown. These hooks Nare cut away at a suitabbeangle upon one side for the purpose of i more perfectly guiding thethread toward the next succeeding bobbin after one of the bobbins hasbeen filled. These hooks, as soon as the shifting mechanism moves thethreads at an angle, which is done as soon as the bobbins being woundare filled, catch the threads and shift them over toward the nextbobbins. After each one of the bobbins on all of the differentholding-bobbin shaftshave been filled the belt is shifted from the tightto the loose pulley upon the driving-shaft, so as to stop the machine,and then the different shafts G are removed, the filled bobbins takenoff, and empty ones put in their places, each pair of empty bobbinsbeing separated, of course, by the hooked disks,'as above described. Thebobbins and disks are clamped together on their shafts by the nuts I),and are thus caused to revolve with their shafts by frictional contactalone.

Gearing with the wheel or gear 0, on the inner end of the maindriving-shaft,is a wheel, 0, upon the lower end of the shaft P, whichhas the gear Q also secured to it. This gear Q meshes with a largerwheel, R, placed upon the shaft S, which is provided with asmallerwheel, T, for engaging with a larger wheel upon another shalt. Therewill be any desired number of shafts provided with wheels,which are ofdifferent sizes, for the purpose of decreasing the speed from the mainshaft. The object in using a decreasing mechanism is to impart to theshaft U about one revolution to driving-shaft B.

every six hundred revolutions of the main I do not limit myself to theparticular decreasing mechanism which is here shown, for any otherequivalent mechanism that will answer the same purpose may be used. Theobject of giving such a relatively-slow movement to the shaft U is toonly operate the shifting mechanism when the bobbins have been filled.

Upon the shaft'U is secured a wheel, V, which carries a projection orpin, W, which engages with a corresponding projection, X, upon the slideY at every revolution of the wheel V, for the purpose of moving theslide endwise. Connected to this slideis a suitable spring, Z, whichreturns the slide to position as soon as it is free-to move. Connectedto the inner end of this slide Y is a spring-aetuated dog, A, whichengages with the ratchetwheel B, placed upon a short shaft, 0'. A seconddog, A, or friction-brake of any kind, is used in connection with theratchet-wheel B for the purpose of preventing any backward movement asthe slide Y is being drawn backward. Each time that the slide is movedendwise by the wheel V the dog causes the ratchet-wheel to movepartially around. In order to regulate the distance that thisratchet-wheel B shall be moved, a regulatingstop, D, is placed upon thesupport E, upon which the slide and dog move. When it is desired thatthe ratchet'wheel B shall be turned one, two, or more teeth, thisregulating-stop, which is provided with slots D and held in position byset-screws D, is moved accordingly. In order to increase or decrease thetension of the spring Z, a corresponding slotted stop, F, is also used.This stop F, by being moved inward, increases the tension of the spring,and by being moved outward decreases it. By means ofthe stop forregulating the movement of the slide Y, the distance that the shiftingmechanism is moved is regulated.

Placed upon the shaft 0 is a spur-wheel, G, which engages with the rackH upon the carriage I. This carriage I is provided with suitablefriction-rollers, J, which move upon the two guides K. The upper one ofthese guides K is secured to the lower one by means of the two springsc", as shown, so as to allow the guide to move vertically, and thus givein case the carriage encounters any obstruction, and at the same timethe movable guideacts as a brake upon the carriage to prevent it frommoving too readily. If the guides K are made stationary, they are liableto hold the carriage too tightly, and if one of the guides is madesimply adjustable vertically without being made to exert any pressureupon the carriage, then the carriage is liable to move further than isnecessary or desirable. This carriage is provided with a number oftension mechanisms, M, of any suitable construction, according to thenumber of bobbinshafts which are used. The-spools N from which thebobbins are to be filled are placed upon suitable holding devices, andthen the thread is passed from these spools through the tension devicesupon the carriage to the bobbins. WVhen the first bobbins upon the shaftG are being filled, the carriage is moved inwardlyas far as possibletoward the spools; but as the bobbins are gradually filled the carriageis moved endwise by means of the spurwheel upon the shaft 0. WVhen thecarriage has been moved its full distance, the bobbins upon the shafts Ghave all been filled,and the machine is stopped by shifting the beltfrom the tight to the loose pulley. Then the clamp 1?,connected to thesupporting device E, upon which the slide, dog, wheels, and shaft 0 areplaced is loosened, and then the spur-wheel upon the shaft 0 is movedback out of contact with the rack upon the carriage, and then thecarriage can be moved freely back into position.

The clamp P consists of a simple bolt which passes through the slot atin the. frame into the bracket a of the sliding frame E, and thus holdsit in position.

The supporting device E consists of a sliding table having a bracket, awhich is dovetailed in the frame, and which can be moved horizontally byhand,for the purpose of moving the wheel G in and out of gear with therack H. After the wheel has been moved in gear the supporting device ortable is locked in place by the clamp P.

Having thus described my invention, I claim 1. The combination, with therevolving shafts and a driving mechanism for causing them to revolvewith the bobbins placed thereon, of the disks provided with hooks andplaced between the bobbins, substantially as described.

2. The disk M, having recessed sides so as to correspond to the shapesof the bobbins, and provided with the hook N, for the purpose oftransferring the thread from one bobbin to the other, substantially asset forth.

3. The combination of the shafts upon which the bobbins are placed, amechanism for driving them, the disks placed between the bobbins, asliding carriage which guides and moves the threads from one bobbin toanother, and mechanism, substantially as described, for shifting thecarriage and moving the threads as fast as the bobbins are filled,substantially as specified.

4. The combination of the driving shaft provided with pulleys, theshafts F, provided with pulleys E,the belts for driving the shafts F,the shafts G, means whereby shafts G are connected to'the shafts F, thehooked disks, the sliding carriage, and mechanism, substantially asdescribed, for moving the carriage as the bobbins become filled,substantially as shown.

5. The combination of the driving-shaft, a train of reducingwheels, theshaft U, the wheel V,provided with an arm for moving the slide, thespring-actuated slide carrying a dog, the ratchet-wheel, a spur-wheel,the carriage which is moved by the spur-wheel, the tension devices forholding the threads, the shafts 'G, and operating mechanism for causingthe shafts to revolve, and the disks, substantially as described.

6. In a bobbin-winding machine, the combination of the shafts upon whichthe bobbins are placed with the disks which separate the bobbins, andwhich are provided with hooks and V-shaped edges, substantially as shownand described.

In testimony whereof I affix my signature in presence of two witnesses.
